"Microsoft's free Shared Computer Toolkit lets you configure a PC that can be used to search the Internet, look up resources, and run approved programs; it also stops users from making permanent system changes, running arbitrary programs, or introducing malware. Administrators on domain-based PCs have long been able to do this; the toolkit offers a similar level for any PC. You don't need an IT degree - the kit leads an administrator through the steps of locking down a system."
